What are the three days of 7 days and 3 inspections?

The 7-day and 3-day tests are 1, 3 and 7 days respectively.

Three nucleic acid tests in seven days means that three nucleic acid tests are completed in seven days, and the time of these three nucleic acid tests is 1, 3 and 7 days respectively. COVID-19 still has a certain incubation period after infection, but according to the current data, the average incubation period in COVID-19 is about 3-4 days, and if the nucleic acid is detected only 3 days ago, it may be undetected, leading to missed diagnosis and misdiagnosis. Therefore, in order to ensure the accuracy of nucleic acid detection, the accuracy of 3 tests in 7 days will be higher.

Within 7 days, the following personnel will be given a yellow code.

1, the time and space of confirmed cases or asymptomatic infections intersect.

2. People who have lived in cities and counties where high-risk areas are located or potential communities to spread risks.

3. People who have lived in the city and state where the moderately dangerous area is located.

4, the occurrence of local epidemic may lead to long-term spread in the province.

5 nucleic acid testing should be carried out regularly in the province according to the relevant requirements, and the yellow code should be given if it is not tested within the time limit.
